Application & fit

The Legris 3109 14 17 is a push-fit elbow trap designed for vacuum applications where a 14 mm tube must connect to a 3/8 in MBSPT port. It suits installers who need a compact, tool-free joint in confined routing. Buyers who require a straight coupling or a different thread standard cannot use this fitting.

Thermals, noise & power

The fiberglass-reinforced nylon body is rated for a maximum operating temperature of 175 degrees F and a maximum operating pressure of 290 psi. Pre-applied thread sealant on the MBSPT side helps maintain a leak-free seal without additional compounds. No moving parts or electrical elements are present, so the component adds no audible noise or power draw.

Deciding specification

The defining parameter is the 14 mm push-to-connect tube size paired with a 3/8 in MBSPT male thread, which fixes both the tube and port compatibility in a single elbow form factor. If your system uses a different tube diameter or thread type, this part will not fit.

Questions about this item

How do I install the 14mm push-to-connect side and the 3/8in MBSPT thread side without leaks?

Push the 14mm tube firmly into the fitting until it seats; for the 3/8in MBSPT thread, hand-tighten then turn one to two more turns — the pre-applied sealant does the sealing, so do not add tape or paste.

What maintenance or replacement will the fiberglass-reinforced nylon body and pre-applied thread sealant need over time?

Inspect the 14mm collet and O-ring annually; replace the fitting if the collet no longer grips or the sealant on the 3/8in threads shows wear — the sealant is single-use and cannot be reapplied.

Which limit appears first during sustained use: the 290 psi pressure rating or the 175 °F temperature rating?

The 175 °F temperature limit is reached first in hot-water or steam lines; above that temperature the fiberglass-reinforced nylon softens and the 290 psi pressure rating no longer applies.
